SELF-CARBONATING APPARATUS.

Application filed larch 81, 1928. Serial No. 98,918.

This invention relates to self carbonating apparatus and is more particularly directed to a carbonating apparatus or means adapted to carbonate water for use lll'COIlIleCt-IOII 6 with syrups, such as root beer or the like.

An ob'ect of this invention is to provide a self car nating apparatus which is comact in form and easily portable and which 18 ads. ted to be employed in connection with m the sa e and distribution of root beer or like flavors in barrels.

Another object of this invention is to provide a self carbonating apparatus in which means are provided for percolating Water downwardly against an upwardly risin stream of carbon dioxide.

other object of this invention is to provide means for breaking up an inflow of carbon dioxide into minute gas particles as m the same passes into the water.

Another object of this invention is to provide a. float valve mechanism adapted to regulate and control the admission of water into the carbonating apparatus.

35 Other objects and advantages of this invention will be a parent from the following detailed description of a preferred embodiment thefleof as illustrated ii:1 the accoman rawin in which rawings: p 1 is a s e ctional side elevation of a self carbonating apparatus embodying this invention.

Figure 2 is an enlarged central section of the valve mechanism embodying this invention.

In the referred embodiment of this invention i lustrated in the accompanying drawings, 1 illustrates a tank which may be of any desired or preferred form and which 46 is provided with a flange 2 at its upper end to which a flange cover 3 is secured by bolts 4. The shell of the tank 1 is also flanged outwardly at its bottom as illustrated at 5 and secured to a bottom plate 6 by means of bolts 7. A fusion stone 8 (a porous stone through which the carbon dioxide percolates and is dispersed) of any desirable construction, as is well. understood in the art, is mounted at the bottom of the tank 1. A wire 50 screen 9 is secured between the flanges of the tank 1 and cover 3 at the upper end and extends over the upper end of the tank' 1. A plurality of multiplicity of fine glass balls 10 are mounted u n the screen 9 so that as the water is admitted into the tank 1 from the inlet pipe 11, the water is broken up into small drops and driven into the tank 1 into the as present in the space above the water levei 'as illustrated at 12. The dripping of the water through the gas space greatly increases the surface area of the water admitted into the-tank and permits a greater efliciency of carbon dioxide absorption b the descending water. The carbon dioxide is admitted into the tank 1 through a pipe 13 from any desirable or suitabl source. the pipe 13 being connected through the plate 6 with the interior of the tank 1 as illustrated at 14.

The carbon dioxide admitted into the tank 1 passes over the fusion stone 8 above which a second screen 15 is supported and u on which screen 15 a multiplicity of fine g ass balls 16 are mounted so as to distribute the carbon dioxide and increase the surface area thereof so that the absorption between the carbon dioxide and the water will increased during the admission of the carbon dioxide.

Means are provided for regulating the inflow of the water to the tank 1 so as to maintain a definite level of water within the tank 1, which means preferably comprise a float 17, which float 17 is secured to a float guide rod 18 at its lower end. The float guide rod 18 asses,through and is guided by a float gulde '19 formed on the-bottom plate 6. The float guide 19 is in the nature of an up r projection formed on the plate 6, and w ich projection has a bore 19" formed therein into which the rod 18 passes. 'The float 17 is secured to a rod 20 at its 'upper end, which rod 20 is secured at its upper end to a valve seat 21. The rod 20 extending through the valve seat 21 is secured at its upper end to a head 22.

The water inlet pipe 11 is securedto the cover 3 by means of a coupling member 23 which is screw-threaded at the boss 24 to the cover 3. The coupling member 23 has 100 an interior bore 25 in which the head 22 is mounted. A web 26 is formed across the bore 25 at its lower end and has a bore through which the rod 20 extends. A compression spring 27 is mounted on the rod 105 20 between the head 22 and Web 26. A valve seat 28 is formed at the lower end of a coupling member 23 and is adapted to be engaged by the valve head 21.

It will therefore be seen that as the level no of the water drops in the tank 1, the float 17 will drop and move the head 21 away from the valve seat 28 and permit water to enter from the inlet 11. The spring 27 yieldably urges the valve head 21 towards the seat 28 so as to form a fluid tight valve closure when the level of the water in the tank 1 is at a predetermined height.

Having fully described a preferred embodiment of our invention, it is tobe understood that we do not wish to be limited to the exact details herein set forth, which may obviously be varied without departing from the spirit ofour invention as set forth in the appended claims.

We claim:

1. In a device of the class described, the combination of a container, means for admitting water to the top of the container, a screen mounted across the top of the container, water distributing means mounted upon the saidscreen for distributing the said water to cause the same to drip through the screen in drops, means for admitting gas to the bottom of the container, a screen mounted at the bottom of the container below the normal water level, and gas dis tributing means mounted upon the said a screen and means mounted within the container for controlling the admission of water 2. In a device of the class described, the combination of a container, means for admitting Water to the top of the container, valve means for controlling the admission of water to the said container, means for admitting carbon dioxide to the bottom of the container, float means for actuating the said valve to maintain a predetermined water level in the said container, guide means formed on the bottom of the said container for guiding the said float means, and carbon dioxide diffusion means mounted on the bottom of the said container and through which the said guide means extends.

3. In a deviceo f the class described, the combination of a container, means for admitting water to the top of the container, means mounted within the container for controlling theadmissionot water to the said container, means for admittin'g gas to the said container, a fusion'stone mounted at the bottom of the container, a screen mounted on the fusion stone, anda plurality of distributing members' mounted'l bn the said screen for distributing the said gas into the water within the said container.
